4. Explain the concept of positive feedback. Give an example of a hormone that
works through positive feedback.
1- Positive feedback is the action of a hormone increasing the production of that
hormone. (This is the opposite of negative feedback). 2- One example is the
action of oxytocin causing the uterus to contract during labor. Oxytocin enhances
the effect of the uterus contractions, causing more oxytocin to be released. The
positive feedback loop is stopped once the baby is born and the uterus no longer
needs to contract, stopping the production of oxytocin.
This type of hormone is derived from cholesterol:
A. Peptide hormones
B. Catecholamines
C. Steroid hormones
D. Tyrosine
C
Label the endocrine glands (A-D) A: ______________ B: ______________ C:
______________ D: ______________
A: Thyroid gland B: Adrenal gland C: Kidney D: Pancreas
, 2
3. Label the endocrine glands (A-C)
A: Pineal gland B: Hypothalamus C: Pituitary gland
Explain the concept of negative feedback and how it helps to maintain
homeostasis.
1- The effect or increased level of the hormone acts to shut down the con!nued
release of the hormone. 2- The brain is constantly monitoring hormone levels to
keep levels within a certain range or set-point (homeostasis). Nega!ve feedback is
a way of "turning off" hormone produc!on when the desired level is achieved
5. This type of hormone is derived from proteins:
A. Peptide hormones
B. Catecholamines
C. Steroid hormones
D. Tyrosine
A
6. Growth hormone____
A. is most active during childhood/adolescence.

6. Growth hormone______
A. is most active during adulthood.
B. is produced by the anterior pituitary gland.
C. underproduction is called acromegaly.
D. A &C

7. Neurosecretory cells are a part of what endocrine organ? Thalamus
Pituitary
Cerebellum
Hypothalamus
Hypothalmus
7. Neurons in the hypothalamus are called ______
